(From company literature) Tamrac 5578 Expedition 8. The Expedition 8 is Tamrac’s largest backpack for carrying the most extensive collection of photo equipment. Dual "wing" pockets with water-resistant zippers organize and provide quick access to important accessories without disturbing your other gear. These "wing" pockets also feature Tamrac's patented Memory & Battery Management System™ that uses red flags to identify available memory cards and batteries from ones that are used up. A tripod is cradled (centered and balanced) securely between these pockets with Tamrac's QuickClip™ tripod attachment system while the lower plastic-reinforced Tripod Foot Pocket holds two tripod legs secure.

A large front pocket with a water-resistant zipper holds a light jacket or extra gear. The main compartment is completely foam padded with numerous adjustable, foam-padded dividers to protect multiple pro-size digital or film SLRs, a full range of lenses, and flashes. A camera with a long zoom lens attached is suspended on two vertical, foam-padded dividers that are internally reinforced with rigid plastic. Restraint straps hold the lens firmly in place. Three Windowpane-Mesh™ pockets inside the front flap visibly organize filters, film and other accessories. A plastic, foam-padded platform in bottom provides shock protection while a LockDown™ rain flap protects the zipper from the elements.

The state-of-the-art harness system features Dual-Density Comfort Pads that provide maximum carrying comfort while Air Flow Channels help keep you cool and dry during extended use. The pack is also equipped with a BioCurve™ dual-pivoting waist belt to provide a wide range of adjustment. Cinch straps on the shoulder harness and waist belt, and an expandable sternum strap allow finer adjustments for maximum comfort. The harness also features "D" rings that accept Tamrac's optional backpack camera strap (Model N-11).

Pros:

build quality, ergonomics

Cons:

heavy

When me and my wife were on our honeymoon, it became clear that she can't carry her camera with all the accessories.
The only solution was for me to carry all our equipment.
I'm talking about 2 Nikon D70's with full sets of lenses and accessories.
About the only bad that could include all our stuff was the tamrac's Expedition 8.

The bag is very comfortable (especially the hip belt) and allowed me to carry a 10kg bag for days.
Build quality is excellent.
The whole bag is well thought out.
I have also purchased an additonal filter pouch and it's very useful as it is kept available at all times, but using it with the 77mm filters is somewhat problematic - at least I tent to leave fingerprints on the glass
There are several ways to attach your tripod to the bag and it's possible to carry a very heavy tripods that way w/o requiring a rest every 30 minutes
Due to all the protection and dividers, the bad is a bit heavy even when empty

Bottom line:
Great bag, but use it only if you really need to carry *all* this equipment on that day.
Othersiwe it would be wiser to take a smaller bag.
